Checking the S.M.A.R.T. status of your hard disk

Disk drives you use with your computer can include S.M.A.R.T. hardware that tests and monitors the drive continuously for potential problems and failures. You can check the S.M.A.R.T. status of your hard disks in Disk Utility.

S.M.A.R.T stands for Self-Monitoring Analysis and Reporting Technology.

If the S.M.A.R.T. status for a disk shows "Verified," nothing is wrong with it. If you see "About to Fail" in red letters, you should back up the disk and replace it as soon as possible.

In Disk Utility, select a hard disk in the list of disks and volume. Look at the bottom of the window for the S.M.A.R.T. Status.
